Moon Square Moon Synastry
If you have ever read the book "The Five Love Languages", you would understand what a moon square moon synastry is like. What makes YOU feel emotionally heard, understood, secure and seen is NOT what they are accustomed to, not what they need emotionally and not the language they were raised to speak. Your mothers raised you very differently, your mothers are probably very different and most likely do not get along. If you are a woman, his mother will probably butt heads with you. Unfortunately, it needs people who are very self-aware to make this synastry work out as most people refuse to accommodate to their partner's love language and simply say " I was born this way, this is my way of expressing my emotions/love"
For me, I understood his love language and tried my best to accommodate his emotional needs without him asking but unfortunately, for example with my love language which is physical touch, I have to ask for it and demand it everyday which gets tiring. Although he would do it tbh but not without me asking and I'm talking we'd been together for 6 years. This, for example wouldn't be the case with moon conjunct moon synastry, as he would understand your emotional and physical needs intuitively and most likely he would have the same language and needs. With the square, it's intentional work and with love languages, it can be taught but when it comes to how you express your emotions, like for example, if you have a fire moon and they have a water moon, it can get frustrating when one needs direct communication and self-expression immediately and the other bottles things up or avoids confronting emotions.
You love each other deeply, no doubt, but the friction of your emotional worlds and needs is drastically different and sometimes you crave someone to understand you without having to constantly explain what you need especially when you are at your lowest.
